ABSTRACT:
An infinitely variable speed, power transmission unit and method in which three torque responsive bodies are shifted between driving, reaction and driven functions to effect alternate modes of operation in which two or more contiguous ranges of infinitely variable speed ratios are provided at high power transmitting efficiencies. Two of the three bodies establish a variable traction surface radius factor by which speed ratio is made infinitely or continuously variable in the range of each mode. The radius ratio factor is related to the gear ratio factor of alternately operable unit gearing in a way to enable the speed ratio range in one mode of operation to be an extension of the other mode. The unit enables synchronous shifting between operating modes in the sense that the radius ratio factor is varied in alternate directions between minimum and maximum values in any two of the respective alternate modes of operation.
